SPECIFICATION forming part of LettrsPatent No..372,75`3, dated November 8, 1887.

` Application tiled January E, 1387. Serial No.- 223,771.' 4(Nommlel.) i

Be it known that I, HARRIS P. HURST, a citizen of the United States, residing at Summit, in the county of Iike and State of Mississippi, havein vented certain newand useful Improvements in Projectiles for Ordnance; and I do declare the following to be' a t'ull, clear, and exact .description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part ot' this specification.

My invention relates to an improvemcnt'in projectiles for ordnance; and it consists in a projectile having a longitudinal fuse or ignition chamber and radial charge-chainbers communicating at their inner ends with the fuse or ignition chamber, whereby the said charge eham bers will be, dischar ,re d Vduring the flight of the projectile.

My invention further consists-in the peculiar construction and combination of devices,

Vthat will be more fully set forthhereinatter,`

and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a longitudinal central sectionall view ot' a projectile embodying my improvements. Fig. 2 is a transverse sectional view of the same, taken on'the line 'x a: ofFig. 1.l Figs. 3.and4 illustrate modified forms of my invention.

- Fig. .5 is a detail sectional view of a ixed charge of powder and ball for one of the chambers of the shell, arranged in the formof cartridge. Fig. 6 is a detail sectional-view of a modification, showing the manner of firmly securing a ball in a charge-chamber.

A represents an elongated projectile, which is made ofiron or'steel, and is provided with a central lougitudinalvbore or chamber, B, which extends nearly throughout the length of the projectile, and is open at its rear end. The front end of the bore or chamber I is enlarged to form a chamber, C, in the head of the projectile. A

. E represents a hollow tube which is located in the bore ot'. the projectile. yThe front endof 'the tube is gradually enlarged to enableit to snugly fit inthe front end of the bore, as atl",

the remaining portion of the'tnbe being ot less diameter than thel diameterof the bore, and thereby an annular chamber, G, is formed 1ongitud-lnally in the center of the projectile, and

surrounding the tube. The rear end of the latter, is closed, and its front end `is open and 'communicateswith the chamber C. Channels H are made in the sides of the enlarged portion F ot the tub'e to communicate with the chambers C and G.

The projectile is honeycombedand pro# vided throughout nearlyits entire length with a series of radial cham'bers, I, of any desired Each radial chamber I is loaded-with pow-v der and ball, the-chamber C and the .hollow Fig. 3, or reartube are charged with powder, and the annular chamber G is charged with a suitable ful-l niinatng fusel or' slow-.burning powder. A

ti1ne-fusc, K, is placed over the rear end of.

the chamber G, and is adapted to ignite the contents of the chamber Gat any desired length of time after the projectile has been tired from the cannon and while the projectile is in flight.

at long or short ranges, and the operation of thcsameis as follows:

The time-fuse is eut to cause the fulminating-fuse powder to be ignited atthe desired distance from the gun, and as the projectile is The projectileis adapted to beused 'with effect against bodies of troops either' in flight through or over the body ot' men `at whom the piece was pointed the eharges'in the chambers I, are successively ignited by the Y fulminating-fuse powder, thereby discharging the balls or projectiles in the said chambers laterally fromy the projectile, and causing at least a portion of them to take effect. After all ot' the chambers I have been discharged, the

fulminating-fnse powder ignites the powderin the chambers C and in the hollow tube, thereby exploding the projectile and blowing vit to fragments with great destructive force.

lOO

Vhen the projectile is-to4 be used against troops formed inv open line of battle,l and not in columns or solid masses, the chamber G will be charged with an instantaneous rapid-burning. detonating powder, so that'all the chambers IWill be discharged at once. In this event the tube E is omitted from the .chamber D, as shown at Fig. 4. In the said figure I also .illustrate the time-fuse at the front end ofthe projectile, as it is sometimes desirable to lo cate the time-fuse at the front end thereof, instead of at the rear end; and I do ,not desire to limit myself in this particular.

` In Fig. 5 I show a.y fixed cartridge-charge of powderand ballforoue of theradial chambers. Y'Having thus described my invention, I elaim Y 1. A projectile having the longitudinalcliarge -ehamber C, a fuse chamber, G, surrounding the saine, and having ysuitable fusecharge, .and the radial chfnge-chmnbers Leoni- 1n unicating at their inner ends with the chamber G, for the purpose setforth, lSubstantially as described.

rounded by and communicating with the chamber G near the extremity thereof', for the pur' pose set forth, substantially as described.'

3. A projectile having a longitudinal chargechamber, a fuse L chamber surrounding the same, connecting at one end with such chargechamber and having,` aprimerconnecting with the'half o f the fuse-chamber remote from thev passage connecting with the chargechainber,

and a series of radial charge-chambers conneeting with the fuse-chamber, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
